TweakJS от P.C

TweakJS is a lightweight extension that gives you full control over what runs on the pages you visit. Add domains and attach JavaScript snippets that execute automatically whenever those pages load.

Use it to personalize site appearance, fix small annoyances, automate tiny tasks, or prototype quick changes — all from your browser.

TweakJS — small scripts, big control. Customize the web the way you want it.
